Zhifei Li

Incoming CS PhD student at Princeton (Fall 2026), advised by Tri Dao and Ravi Netravali. Previously a visiting student researcher at UC Berkeley's Sky Computing Lab with Ion Stoica. B.S. from Renmin University of China.

I work broadly on machine learning systems, with interests in efficient infrastructure, training and inference systems, and the design of systems for emerging AI workloads.

Papers

Code

  • LEANN, 12k stars: a vector index that cuts storage by 97%, so RAG runs locally on a laptop.
  • PixelRAG, 9k stars: retrieval over web screenshots instead of parsed text.
  • SkyPilot, 10k stars: top-10 contributor; built the high-availability controller for SkyServe.
